DELTA MS 20 DRAIN – High-Performance Geocomposite Drainage Sheet

What is a Geocomposite Drainage Sheet?

Geocomposite drainage sheets are advanced drainage systems designed to control and redirect water flow. They generally consist of a structured studded core combined with a geotextile layer, allowing efficient water filtration and drainage.

DELTA®-MS 20 DRAIN combines this technology with high-performance features to provide long-lasting drainage protection for demanding construction applications.
